I wanted to thank everyone for their advice and help. We have kept thorough documentation on this patients abusive behavior and numerous no-show's for her appointments over the last 15 years, so I know we are good there. I have sent a letter of termination to her, and now I will just wait and see what if anything she does about it, like another nasty phone call. I still feel badly about it all, because I know her behavior is due to mental illness, but as Doo said, you don't want to keep someone around who is abusive like this.
